Metal Etching OEM/ODM Micro-Hole Filter Meshes for Filter Industry

Metal Etching OEM/ODM Micro-Hole Filter Meshes for Filter Industry

What is Etching?
Metal etching is a precise, subtractive manufacturing process that uses controlled chemistry to selectively remove material from metal sheets. It produces clean, burr-free parts with complex geometries without heat or mechanical stress, ideal for delicate and high-tolerance parts.

Filter Meshes Overview
Our chemically etched metal filter meshes are engineered for superior performance in filtration, sieving, and fluid control applications. Unlike woven or punched meshes, they offer precise, consistent apertures, smooth surfaces, and excellent structural integrity, enabling exact control over particle retention and flow dynamics.

Filter Mesh Features

• Precise & Consistent Apertures: Every opening is identical in size and shape, ensuring predictable and reliable filtration performance.

• Burr-Free & Smooth Surfaces: No loose wires or debris; smooth edges prevent particle trapping and facilitate easy cleaning.

• High Open Area & Strength: Optimized designs provide maximum flow with minimal pressure drop while maintaining structural rigidity.

• Design Flexibility: Any aperture shape (round, square, slot, custom) and pattern layout are easily achievable.

• Material Versatility: Manufactured from stainless steel, copper, titanium, nickel alloys, etc., to suit various chemical and temperature environments.

FAQ

Q1: What is the difference between etched mesh and woven wire mesh?
A: Woven mesh is made by interlacing wires, which can shift under pressure. Etched mesh is created from a solid metal sheet, offering absolute hole position stability, higher flatness, and no risk of wire unraveling. It is ideal for applications requiring rigid, high-precision filtration.

Q2: What is the smallest hole size you can achieve?
A: We can manufacture holes as small as 0.03mm (30 microns) in diameter, depending on the material thickness.

Q3: Can you produce custom shapes (not just round holes)?
A: Yes. We can produce any 2D pattern, including square holes, hexagonal holes, slots, and complex custom logos or designs, without the need for expensive hard tooling.

Q4: Does the etching process leave sharp edges?
A: No. Unlike stamping or machining, our chemical etching process produces a smooth surface with minimal burrs. We can further optimize the process to ensure safe handling and precise flow rates.

Q5: What is your MOQ (Minimum Order Quantity)?
A: We offer low MOQs. We are happy to support small-scale prototyping as well as mass production orders.

Q6: How do you ensure the uniformity of the holes?
A: We utilize high-precision phototools and controlled etching parameters to achieve a uniformity tolerance of ±0.01mm across the entire sheet.
